I am getting closer to completing my Coho and am planning to varnish with West Marine's Skipper (actually Z-Spar Captain but $2 or so cheaper). While getting some sandpaper, I saw MINWAX Helmsman Spar Urethane cans and the sample wood with the various stain and finish coats on it. The Spar Urethane looked good and was tough. The literature says it contains UV absorbers and is especially resistant to sun damage and protects against moisture, sun, and salt air. Does anyone have any experience with this stuff? Thanks Mike
